About this listen
The CMS Collaboration's "An all-round boosted chase for supersymmetry" explores the concept of supersymmetry (SUSY), a theoretical extension of the Standard Model of particle physics. The article details how scientists at CERN's CMS Experiment are searching for superparticles by analysing final states that include Lorentz-boosted objects, which are formed when heavy superparticles decay into lighter, high-momentum particles. This new "razor boost" analysis broadens the search to 25 distinct final states, including boosted W, Z, Higgs bosons, top quarks, and uniquely, boosted leptonic jets, using machine learning and razor kinematic variables to identify potential SUSY signals. Although no significant deviations from Standard Model predictions were observed, the findings have allowed the collaboration to set strong limits on superparticle production rates and masses within various SUSY models, with further interpretations of complete SUSY models ongoing.
